so.. As far as I can tell, starting with 2.4.19, the kernel has support for 20276. I need to set up (ideally) a bootable Raid 1 on this box. (if not a non bootable Raid 1 would do I guess.) This machine will only be running Linux, so no dual boot to worry about... Which of these two is better (performance and data integrity wise..) ? (I) Use the pdcraid.o module and use the /dev/ataraid stuff... (II) just load the PD 20276 driver as a regular ide controller and use Linux Software Raid to make it /dev/md0 ? Again I am interested in performance and data integrity.. Thx Tons.. PS : and yea tips about making a bootable raid array with Options I or II would be appreciated. I wont be installing Redhat, probably Gentoo or Slackware. And If required I can install to a spare hdd on another controller.. and then create the raid.. and migrate the install and make it bootable.. Thx again Ari __________________________________________________ Do you Yahoo!? New DSL Internet Access from SBC & Yahoo! http://sbc.yahoo.com
